七姊妹山自然保护区蕨类植物区系地理及资源开发研究

运用植物区系地理分析方法对七姊妹山自然保护区的蕨类植物区系特征进行研究。科的地理区系分析表明,热带、亚热带成分高达58.3%,占主导地位。属的地理区系分析也表明了类似的趋势。种的地理区系分析表明,除了热带、亚热带成分占有较高比例外,温带分布的种也具有较高的比例,占非世界广布种的1.2%。特别是世界温带分布的种占较高比例,达24.2%,这反映了温带成分的重要地位。七姊妹山蕨类植物资源丰富,可区分为药用、观赏、食用、指示类植物等几大类。各种蕨类植物资源显示了广阔的利用前景。

Study of pteridophytic flora and resources in Mt.Qizimei Nature Reserve

Based on the investigation and statistical analysis, the characteristics of pteridophytic flora and the pteridophytes resources in the Mt.Qizimei Nature Reserve were studied. The floristic analyses of families,genera and species showed that both the tropical and tropical-to-subtropical elements took a large proportion. The species in temperate zone also have a high proportion. 24 families,47 genera and 119 species of pteridophytes in Mt.Qizimei were recorded. They may be classified into many types respectively used for medicine,ornament and food,etc. According to the characteristic of Mt.Qizimei,some suggestions on how to exploit and utilize the pteridophytic resources of Mt.Qizimei were put forward and some aspects should be strengthen.
